JNDI DATASOURCE PROBLEM WITH WSAD

I am facing a problem of getting connection. I have done changes in ibm-web-bnd.xml(<resRefBindings xmi:id="ResourceRefBinding_1125512347889" jndiName="jdbc/session_borg"> <bindingResourceRef href="WEB-INF/web.xml#ResourceRef_1125512347889"/> </resRefBindings>)

I have added JNDI NAME IN datasource in server perspective. I have added piece of code in web.xml <resource-ref id="ResourceRef_1125512347889"> <res-ref-name>jdbc/session_borg</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> <res-sharing-scope>Shareable</res-sharing-scope> </resource-ref> </web-app>
